A Theoretical Study on the Initial Collection Efficiency of Submicron Particles by a Unipolar Charged Fiber

단일 전하로 하전된 단일 섬유에서의 미세입자의 초기 집진효율에 관한 이론적 연구

In this study, we have developed a simulation method to predict the initial collection efficiency of a unipolar charged fiber in the electret filters. The particle sizes considered were in the submicron range and thus Brownian motion of particles was also taken into consideration along with electrostatic forces acting on the particles. The simulation results were compared with other investigators experimental data on single fiber efficiency as well as with the calculated results using the existing correlations on single fiber efficiency. It has been shown that simulation results are in good agreement both with the experimental data with those predicted by the correlations.
